Crystal Lab
Read full descriptionHide full description
Your next laboratory starts with a tap. Crystal Lab is an idle clicker game where you mine crystals, upgrade equipment, and build a growing jewelry collection. Start small, unlock automatic production, and work your way through five laboratories, each with its own style and tools. Tap to collect raw crystals and decide how to spend them: improve your mining equipment or polish them to buy jewelry. Complete matching sets to earn permanent production bonuses. There is always a new goal to work toward: • Upgrade equipment to increase your earnings per tap and automatic production. • Complete daily missions, open chests, and gather fragments to discover jewelry. • Take on the daily Mining Rush: 30 seconds to keep up your tapping pace and multiply your reward. • Collect sapphire, emerald, amethyst, citrine, and ruby jewelry. • Earn offline progress based on your automatic production. Play at your own pace, plan your upgrades, and turn a small crystal lab into a thriving mining operation.
Model Prisoner
Read full descriptionHide full description
You don't dig your way out anymore. You talk your way out. You're a model prisoner. Build trust with the guard and your cellmate, gather clues, and work for money — three actions a day, spent preparing your escape. ■ Conversation is the game Talk to the guard, your cellmate, and the prison doctor, and pick your responses. Choices move trust up or down and unlock new clues and events. There's no single right answer — it's about the relationship you build. ■ Fill four bars to escape: cash, trust, clues, tunnel progress Each prison sets its own escape requirements. Spend your days working, resting, and chipping away at a tunnel with a spoon, one small step at a time. ■ Ten prisons, new faces each time Escape and you're transferred to the next prison. The guard and your cellmate stay with you, but the doctor and your other cellmate are a different person every time — ten escapes, ten new relationships. ■ Getting caught isn't the end Fail an escape attempt and your suspicion ticks up a little — that's it. Getting caught is part of the story, not a game over. One hand, portrait, a few minutes at a time. Start today's conversation now.

The clearest difference is in-app purchases: Model Prisoner at none against Crystal Lab's 1. Model Prisoner also leads on update cadence (every 2 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
